Not entirely sure, but I would expect COSS to need about the same amount
of memory as the other cache_dir types, or less, not more..

Well, swap has a purpose which is enabling more efficient use of the
memory to avoid needing to have very much memory, but that purpose isn't
really relevant to your server as you have more than sufficient amount
of memory.
It may be possible to tune the VM appropriately to your needs, but
disabling the swap acheives the same thing with less efforts.

Why?

Probably. But keep an eye on memory usage. Only make significant changes
when the memory usage has been stable for a week or two..
It's absolutely no fun to run out of memory. Apart from causing some
significant service disruptions it may also cause you to loose the
entire contents of the cache. Better to be safe than sorry.
